Confirming HDR function is actually in use

Confirming HDR function is actually in use [Monitor]

When connecting an HDR peripheral equipment to an LG 4K monitor, for example, model 32UD99, or playing HDR content on the monitor, customers are looking for reassurance they are benefitting from the full HDR picture quality scope appearing on screen.

Try this

Verify that the environment equipment set-up fully supports HDR so do peripheral devices (player / graphic card) as well as content itself.
The monitor accesses HDR Picture Mode automatically the moment it detects HDR content being played.
There are two ways by which users can confirm HDR function has been activated on their monitor.

1. Acknowledged from the pop-up message at the top right corner of display notifying the user the monitor has made the switch accordingly.
2. Check the Picture Mode on-screen menu. If the Picture Mode menu has changed from the long list of presets to a shorter version of HDR options, then it signifies the monitor has enabled HDR picture mode.
